Recommended Calculators
Inexpensive Calculators (Under $20.00)
Note. Look for calculators which perform two variable
statistics. It will help if the calculator specifically computes the
regression coefficient. Email me if you have found a two variable
calculator which is easy to use and I will add it to the list. A couple of
brands of popular calculators are listed below. More expensive graphing
calculators such as the TI 83 and TI 83-Plus also do two variable
statistics. The following stores in Columbus usually have at least one of
the calculators below: Kmart, Wal-Mart, Target, and Circuit City.
Email me if I have omitted any.
